Glailglind - Tailwind for Gleam

Installs and invokes TailwindCSS CLI.

Heavily inspired by phoenixframework/tailwind.

Compatible with Erlang and Javascript targets. (Javascript target requires curl to be available on the host)

Usage as module

Install Package

gleam add glailglind --dev

Configure TailwindCSS

You can configure TailwindCSS in your gleam.toml by adding a tailwind table:

[tailwind]
version = "3.4.1" # optional
args = [
    "--config=tailwind.config.js",
    "--input=./src/css/app.css",
    "--output=./priv/css/app.css"
]
path = "/path/to/tailwindcli" # optional

This lets you define the arguments being run.

Optionally define a specific TailwindCSS version or the direct path to the TailwindCSS CLI, if you don't want it to be installed automatically.

Install TailwindCSS

gleam run -m tailwind/install

This downloads the Tailwind CLI to ./build/bin/tailwind-cli and generates the tailwind.config.js in the root of the project.

Import Tailwind in your CSS

@tailwind base;
@tailwind components;
@tailwind utilities;

Run TailwindCSS

gleam run -m tailwind/run

Executes tailwind with the defined arguments.

Usage with LustreSSG

ℹ️ Lustre Dev Tools have their own TailwindCSS support!

Install Package

gleam add glailglind

(Optional) Specify version in config

gleam.toml

[tailwind]
version = "3.3.5"

Install TailwindCSS

gleam run -m tailwind/install

Import Tailwind in your CSS

@tailwind base;
@tailwind components;
@tailwind utilities;

Update build script

Import tailwind and add the run step to your build script.

Example:

import gleam/list
import gleam/map
import gleam/io
import gleam/result

// Some data for your site
import app/data/posts

// Some functions for rendering pages
import app/page/index
import app/page/blog
import app/page/post

// Import the static site generator
import lustre/ssg

// Import Tailwind
import tailwind

pub fn main() {
  let posts = map.from_list({
    use post <- list.map(posts.all())
    #(post.id, post)
  })

  let build =
    ssg.new("./priv")
    |> ssg.add_static_route("/", index.view())
    |> ssg.add_static_route("/blog", blog.view(posts.all()))
    |> ssg.add_dynamic_route("/blog", posts, post.view)
    |> ssg.build
    |> result.map_error(fn(e) { string.inspect(e) })
    |> result.try(fn(_) {
      [
        "--config=tailwind.config.js", "--input=./assets/css/app.css",
        "--output=./priv/css/app.css",
      ]
      |> tailwind.run()
    })

  case build {
    Ok(m) -> {
      io.println(m)
      io.println("Build succeeded!")
    }
    Error(e) -> {
      io.debug(e)
      io.println("Build failed!")
    }
  }
}
